TIME DAMPER MECHANISM.

SPECIFICATION forming part of Letters Fatent No. 591,169, dated October 5, 1897.

Application filed April 5, 1897. Slerial No. 680,695. (No model.)

To all whom it may concern.-

Be it known that I, WALTER P. KELLOGG, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in Time Actuated Mechanisms, of which the following, taken in connection with the accompanying drawings,

' is a full, clear, and exact description.

My invention relates to devices for automatically releasing a mechanism at a fixed and predetermined'time of the class shown and described in the patents heretofore granted to meviz., No. 415,389, dated November 19, 1889, and No. 482,366, dated September 13, 1892.

My object is to produce a tripping mechanism in which the falling and tripping lever is pivotally mounted and is released to swing by the clockwork-trip shown in my Patent No. 415,389, and by such lever action a weight always connected to and adapted to slide upon or traverse said rod is released to fall, or said lever is connected to or forms an armature to make a circuit, and when released swings and breaks such circuit, or is connected to a valvestem and operates to shift a valve either to open or close it. All this is accomplished by pivoting the trip at one end and weighting the free end, means being provided to connect it tothe clock-trip. When a falling weight is used, it is permanently connected to said rod and does not become disconnected therefrom when said rod swings. It is constructed as follows, reference being had to the accompanying drawings, in which- Figure 1 is a front elevation of my invention arranged to operate the main and check drafts of a furnace or heater. Fig. 2 shows it as arranged to make and break an electrical circuit. Fig. 3 is a cross-section detail on line X X in Fig. 4. Fig. 4 is an enlarged elevation of an arrangement of the swing-rod as an armature. Fig. 5 is an elevation of the same arranged to open or close a valve in a pipe. Fig. 6 is a vertical section of the valve and pipe, showing the valve closed ready to be opened at the time appointed.

to this precise construction.

be released at a predetermined time. This trip is suitably and permanently connected,

as by a chain 3, to the free end of the swinging lever 4, provided with a weight 5, which can be secured thereon, or adjustable, as may be desired, in any suitable manner. The other end is suitably pivoted or hung upon a pivot 6 in Fig. 1 or upon a lug7 in Fig. 2 or upon a valve-stem 8 in Fig. 5. In Fig. l a link 9 is connected to said rod, as by an eye adapted to slide freely upon it. This link is provided with hooks 10, as many as may be desired, to which the cords or chains 11 and 12 are suitably connected. The cord 11 is conducted over a'suitable arrangement of pulleys and connected to a check-damper 13 in the smoke-pipe 14 of a heater or boiler 15. The cord 12 is conducted over a suitable arrangement of pulleys and connected to a maindraft damper 16, and a weight 17 is secured to this cord in such manner as to be raised when the lever 4 is raised and set, as shown, whereby a slack in said cord is created to permit this draft to close. WVhen so set, the checkdamper is open. At the predetermined time the clock-trip is released, said lever swings down, said eye slides thereon,the check closes, and the weight 17 operates to open the main draft. When said lever is reset, said eye is moved overadjacent to its pivot in order to reduce the strain upon the trip. In this construction when several cords or chains are thus connected to said link or lever all will remain so connected at all times without being disconnected therefrom when the trip is released.

In Fig. 2, 18 is a suitable magnet operatively connected by suitable wires (not shown) to any style or class of electrical apparatus as, for instance, a lighting system which it is desired to shut off at a certain time. As here shown, said lever is provided with. arms 19, which constitute a circuit-closer to the stud 20, being pivoted upon the lug 7 as one pole, while the stud 20 constitutes the other pole. I do not, however, limit myself In this instance when the trip is released said lever swings and the circuit is broken. In Fig. 5 said lever is connected to a valve-stem 8, and the valve, suitably set in a pipe 21, is rotated to be opened or closed, as to shut oif gas or let on steam, or for many other purposes when a particular object is to be accomplished at a specified time.

It will be seen that in my prior patents, above mentioned, the entire weight of the weight mechanism is carried directly by the tripping mechanism and that the clock-movement must exert a great force to trip it, and experience has demonstrated that this weight carrying and exertion of undue (yet necessary) force operates to derange the clockmovement, so that it will in a short time fail to operate the trip, as Well as impair its timekeeping. It is to remedy this that this invention was made, whereby, as in No. 415, 389, the weight of the system of cords or chains and also that of the actuating-weight is substantially removed from the-clock-movement and in which the several cords or chains of the system are not detached from this supporting means, as in No. 482,366.

It will be seen that in the present mechanism the clock-movement is substantially only subject to the weight of the ball (which can be Very light) and of the rod, carrying only the minimum amount or a Very small percentage of the weight of the chain system and actuating-weight on account of the closeness of the ring to the rod-pivot.

Having described my invention, what I claim, and desire to secure by Letters Patent, is

supporting medium until said trip is released at a predetermined time permitting said lever to drop and swing upon its pivot and said link to slide along said lever to its free end without becoming detached therefrom and thereby release the mechanism normally supported by said trip, lever and link.

2. The combination with a clock-movement and its alarm mechanism, of a lever pivoted at one end, a trip normally connecting it thereto and supporting its free end, a link normally connected to said lever adjacent to its pivot whereby the greater part of the force of the weight carried by said link is removed from said trip, and means to release said trip to permit said lever to drop, swinging upon its pivot and said link to the free end of said lever and release the devices carried by it without its becoming disconnected from said lever.

In Witness whereof I have hereunto set my hand this 2d day of March, 1897.
